A Dental filling is a way to restore teeth that are damaged by decay back to their normal function and shape. When any dentist gives the filling, he or she first removes the decayed tooth material, cleans the affected area, and then fills the cleaned out cavity with a specific filling material. Dentists consider a number of factors when choosing which type of filling material is best for you. These factors include the extent of the repair, where in your mouth the filling is needed and the cost.
Your restored tooth after root canal therapy could last a lifetime, if you continue to care for your teeth and gums. However, regular checkups are necessary. As long as the root(s) of a treated tooth are nourished by the tissues around it, your tooth will remain healthy.
Fast facts on pain after a root canal. A root canal will treat the diseased tissue (pulp) while preserving the rest of the tooth. A person will be given anesthetic before the procedure, so it is usually no more painful than a typical dental filling. If a root canal fails, redoing it can fix the problem.
